Deprecated inline styles

[vinkla]

To maintain backward compatibility, the following functions have been deprecated and replaced with the new approach:

• print_embed_styles()
• print_emoji_styles()
• wp_admin_bar_header()
• _admin_bar_bump_cb()
• the_block_template_skip_link()

We should keep these in the plugin but add a note about their deprecation. Do we need to make changes for the new functions?

We could probably skip this for now:

In 6.4 this print_emoji_styles() function is now deprecated. Nevertheless, the above method for preventing emoji styles from being printed is retained, even though they are now being printed by wp_enqueue_emoji_styles(). This applies to the other deprecated functions as well, so no developer action is required.
